What, then, is “racism?” It is considerably more than any dictionary is likely to say. It is any opposition by whites to official policies of racial preference for non-whites. It is any preference by whites for their own people and culture. It is any resistance by whites to the idea of becoming a minority people. It is any unwillingness to be pushed aside. It is, in short, any of the normal aspirations of peoplehood that have defined nations since the beginning of history — but only so long as the aspirations are those of whites.

"Pondering the smoking ruins of American racial policy, I wonder whether it isn’t time to say publicly what many, if not most, of both races know: It isn’t working. It isn’t going to work. If it were, it would have. If it were working, we would not need the unending laws to force the races together when they don’t want to be together. If people wanted diversity, it would happen without compulsion." - Fred Reed, January 2, 2014

"Those who rewrite history attempt to hide own disgrace." - Vladimir Putin, January 28th, 2015

Since science has found that both intelligence and personality are 80% genetic, I guess this means every honest geneticist is a racist.

See a problem with this definition yet?

I see no problem with the definition. It is from Merriam-Webster's.

A geneticist can be of the opinion that race is one determinant of human characteristics without believing that it is the PRIMARY determinant of human characteristics.
Science is not based on beliefs anyway. Science is based on the application of the scientific method to arrive at verifiable and replicable conclusions.
